[Dovecot] 1.0-test53 and 'Junk in start of group' messages

[Nicolas.Kowalski at imag.fr]

Hello.

I am using dovecot-1.0-test53 with Maildir mailstore, with pine 4.61 as 
MUA.

I have several folders which cause error messages like 'Junk in start of 
group' in Pine when I read them. I googled a bit for this, and found 
that removing the index file should do the trick, but unfortunately, it 
does not.

What can I do to make these annoying messages disappear ?

Thanks in advance.
